If the equation y=mx+b is used to model a quantity y as a function of the quantity x, why is b considered to be the starting val

blagie [28]

Answer:

This is because even when the quality of the variable x is 0, the value of b still exists and is the starting point for y.

Step-by-step explanation:

To prove this, we start with the base form of the equation and input 0 for x.

y = mx + b

y = m(0) + b

y = 0 + b

y = b

At the movie theater the prince on 1 adult ticket and 4 child tickets is $44 the price of 5 adults tickets and 2 child tickets i

nydimaria [60]

The cost of one adult ticket is $12 and cost of one child ticket is $8.

Step-by-step explanation:

Let,

Cost of one adult ticket = x

Cost of one child ticket = y

According to given statement;

x+4y=44 Eqn 1

5x+2y=76 Eqn 2

Multiplying Eqn 1 by 5

$5(x+4y=44)\\5x+20y=220\ \ \ Eqn\ 3$

Subtracting Eqn 2 from Eqn 3

$(5x+20y)-(5x+2y)=220-76\\5x+20y-5x-2y=144\\18y=144$

Dividing both sides by 18

$\frac{18y}{18}=\frac{144}{18}\\y=8$

Putting y=8 in Eqn 1

$x+4(8)=44\\x+32=44\\x=44-32\\x=12$

The cost of one adult ticket is $12 and cost of one child ticket is $8.
